General XML is not intended to be parsable as a list. But there are lots of tools you can use to extract various patterns out of XML in forms like a list. 

But your data example is huge and I am falling asleep waiting to see if it loads. I looked sideways and it is not that big directly but my browser may be trying to show it as a web page.

How about you copying and pasting a sample of say the first few dozen lines so we see what is in it for the purpose of ...

The schema would be mentioned in an attribute if you know what you are looking for and may be an external file.

So decide what you want, like a list of all titles and use something like xpath().

Hello, All:


	  What would you suggest I do to parse the following XML file into a 
list that I can understand:


XMLfile <- 
"https://chroniclingamerica.loc.gov/data/bib/worldcat_titles/bulk5/ndnp_Alabama_all-yrs_e_0001_0050.xml" 



	  This is the first of 6666 XML files containing "U.S. Newspaper 
Directory" maintained by the US Library of Congress discussed in the 
thread below.  I've tried various things using the XML and xml2.


XMLdata <- xml2::read_xml(XMLfile)
str(XMLdata)
XMLdat <- XML::xmlParse(XMLdata)
str(XMLdat)
XMLtxt <- xml2::xml_text(XMLdata)
nchar(XMLtxt)
#[1] 29415


	  Someplace there's a schema for this.  I don't know if it's embedded 
in this XML file or in a separate file.  If it's in a separate file, how 
could I describe it to my contacts with the Library of Congress so they 
would understand what I needed and could help me get it.


	  Thanks,
	  Spencer Graves


p.s.  All 29415 characters in XMLtext appear in the thread below.

Hello Spencer,

So, when I view the xml, I'm actually looking at it in XML editor 
software, so I can view the tags and it's structured neatly. I've copied 
and pasted the text from the beginning of the file and the first 
newspaper title below from my XML editor:

When I view the records in the XML editor, these 2 lines below do begin 
each of the records for each individual title, but of course this is 
including the xml tags:

<recordSchema>info:srw/schema/1/marcxml</recordSchema>
<recordPacking>xml</recordPacking>

Hopefully this helps you decide where to break or parse each record.

On another note, I just noticed as well that at the top of this first 
file it lists the total number of records for the Alabama grouping - 
2250. This also appeared to be the case for the Alaska records when I 
took a look at the first one for that state. I imagine that should be 
consistent throughout each "grouping" of records.

Let me know if you have follow-up questions!

Best wishes,

Hi, Kerry:


Thanks. I understand the chunking in files of at most 50. I've read
the first file "ndnp_Alabama_all-yrs_e_0001_0050.xml" into a string of
29415 characters, copied below. Might you have any suggestions on the
next step in parsing this? Staring at it now, it looks splitting on
"info:srw/schema/1/marcxmlxml" might convert the 29415 characters into
shorter chunks, each of which could then be parsed further.


This is not as bad as reading ancient Egyptian heiroglyphics without
the Rosetta Stone, but I wondered if you might have something that could
make this work easier and more reliable? I guess I could compare with
what I already read as JSON ;-)


Thanks,
Spencer Graves

Hello Spencer,

Thank you for reaching out about the bulk xml files for the US Newspaper 
Directory.

We don't have documentation specific to these bulk xml files, but upon 
further inspection I can say that each of those files don't necessarily 
contain info for 50 newspaper titles. The structure of the titles for 
California and New York for instance are different from say, Alabama.

If you look at California for example, the file naming structure 
indicates the year the title started, and then the number of titles 
included in that xml file. So for instance, the files below include info 
for newspapers that started in 2000, 2001, and 2002 respectively. And 
there is info for 30 titles in the xml file from 2000, and 14 in the 
file for 2001, and so on.

   * ndnp_California_2000_e_0001_0030.xml
   * ndnp_California_2001_e_0001_0014.xml
   * ndnp_California_2002_e_0001_0012.xml

If there's more than 50 titles for a given year, say for California 
starting in 1880, then the next 50 titles will roll into the next xml 
file, and so on. And the last xml file for that year may not include 50 
titles.

Many of the states seem to group all the years together, so each xml 
file contains 50 titles, until possibly the last one for a given state, 
which may contain less.

I hope this information helps explain the total number of records and 
structure a bit better. Let me know if you have any further questions.

Best wishes,

Hi, Kerry:


Might there be documentation on the XML files you mentioned?


I've successfully read
'https://chroniclingamerica.loc.gov/data/bib/worldcat_titles/bulk5/',
extracted the names of 6666 XML files, and read the first one,
"ndnp_Alabama_all-yrs_e_0001_0050.xml". It contains 29415 characters,
beginning, "1.12250info:srw/schema/1/marcxmlxml00000nas a22000007i
45001030438981180404c20159999aluwr n 0 a0eng ". With a bit
more effort, I will likely be able to parse all 6666 of these. The
names suggest that each contains information on 50 newspapers, totaling
333,300. The main page
"https://chroniclingamerica.loc.gov/search/titles/" says there are only
157,521 "Titles currently listed". This suggests that these XML files
include place holders for a little more than double the number of
entries currently in "https://chroniclingamerica.loc.gov/search/titles/".


Thanks for this.


Progress.

Hi Spencer,

I thought of one more option after I emailed you yesterday that I wanted 
to make you aware of.

I had explained the other day how we pull the records from OCLC into our 
U.S. Newspaper Directory. You can also access all of the raw MARC 
records found in the directory in xml format from here if you choose: 
https://chroniclingamerica.loc.gov/data/bib/worldcat_titles/bulk5/ 
<https://chroniclingamerica.loc.gov/data/bib/worldcat_titles/bulk5/> These will 
provide you all of the data from the record fields in MARC format, so 
you'd get all the data you see here for example: 
https://chroniclingamerica.loc.gov/lccn/sn98059792/marc/ 
<https://chroniclingamerica.loc.gov/lccn/sn98059792/marc/> but in xml. I 
don't know if this might be more data and info than you want to work 
with, but wanted to make sure you were aware of this option as well.

Best wishes,

Hi Spencer,

Thanks for reaching out again. I have been looking at the json view a 
bit closer this morning and your example of "9999."

After talking with a colleague this morning and looking at various 
examples, I see there is some variation in how the titles with either an 
unknown starting/ending date or currently published titles are being 
handled - depending on the view.

As an example, I completed a search in the directory for Alaska and the 
city of Anchorage. There are 80 results, and on the first page of 
results you'll see # 4. Fort Richardson news, which was published from 
1952-19??. The csv view of this state/city search result will show the 
ending date of 19??. But if I append &format=json to this search result, 
this specific title will show an ending date of 1999. After talking with 
a colleague this morning, I discovered an integer had to be used in 
these cases where dates were "?" so that the search based on year range 
would work. Similarly, if you look at # 12 Alaska digest, which was 
published 1994-current, the "current" becomes "9999" in the json view. 
So, the records you are seeing with "9999" would most likely be titles 
with an ending date of "current."

However, there is an issue with the unknown dates, like "1999" being 
used for "19??" in the example above. The "9" does not get inserted in 
place of "?" when you are looking at the title/LCCN view of a specific 
newspaper. So for instance, if you view the #4 title: Fort Richardson 
news at this url: https://chroniclingamerica.loc.gov/lccn/sn98059792/ 
<https://chroniclingamerica.loc.gov/lccn/sn98059792/> but append .json 
to the end of the url, after the LCCN, like this: 
https://chroniclingamerica.loc.gov/lccn/sn98059792.json 
<https://chroniclingamerica.loc.gov/lccn/sn98059792.json> you'll see 
that the end_year is "19??." Viewing the title/LCCN json view for titles 
that are currently published will also show the end_year as "current." 
The Alaska digest example from above can be viewed here: 
https://chroniclingamerica.loc.gov/lccn/sn97060056.json 
<https://chroniclingamerica.loc.gov/lccn/sn97060056.json>

I wasn't aware of the difference between the directory search json view 
and the title/LCCN view. But I think it would be possible to grab 
the data from the title/LCCN json url through an additional script 
potentially. The json url is included in the view under the "url" field.

Of course, there are unknowns with publishing dates, but better to know 
where the question marks are, and what titles are considered to be current.

I hope this clarifies the data a bit more - let me know if any of it 
needs more clarification though. And let me know if you have follow-up 
questions.

Thank you,

Hi, Kerry:


What would you suggest I do to get a count of the numbers of
newspapers and publishers operating by year from, say, 1790 to 2021?


I just determined that 20630 (13 percent) of the 157520 records in
the US Newspaper database I downloaded a week ago have end_year = 9999.
I don't think it's feasible to assume that all or even most of those
are still publishing.


Might there be some other database that might have this kind of
information?


I ask, because Robert McChesney (2004) The Problem of the Media
(Monthly Review Pr., esp. pp. 34-35) suggests that in the first half of
the nineteenth century, the US had more newspapers and newspaper
publishers per capita than any other place or time. He suggests that
that diversity of newspapers helped encourage literacy and limit
political corruption, both of which helped propel the young US to its
current dominance of the international political economy. I'm hoping to
get some data to evaluate this claim. Sadly, it looks like there is too
much missing and questionable data in this dataset for me to use this
without a fairly substantive data cleaning effort.

Hello Spencer,

Thank you for reaching out about your additional questions.

I was looking at the records you mention above, and yes, you are correct 
- those 9 records with the date inconsistencies and the one record for 
the The New Mexican mining news 
<https://chroniclingamerica.loc.gov/lccn/sn93061507/> containing "Santa 
Fe.\" have typos in them. Thanks for spotting these - it may be possible 
to have the cataloger in our division correct those typos. I will look 
into this further.

The U.S. Newspaper Directory doesn't have a connection with Wikimedia or 
Wikipedia. The Library of Congress periodically pulls the records for 
the Directory from OCLC Worldcat 
<https://www.oclc.org/en/worldcat.html>. And those newspaper records in 
OCLC Worldcat have been created by catalogers at various institutions 
around the U.S. over the span of several years. So, occasionally, you 
will find a typo in the records. Corrections can be made by OCLC and 
library staff at the various institutions. Every time we complete a new 
pull on the OCLC records, any corrected records will then populate our 
Directory.

Regarding your question on the New-York weekly journal - yes, that is 
also correct that it has two records. There is actually a record for 
each format of the newspaper, so this record is for the microfilm format 
<https://chroniclingamerica.loc.gov/lccn/2009252748/> and this one is 
for the original print format 
<https://chroniclingamerica.loc.gov/lccn/sn83030211/>. You can see in 
the heading for the microfilm record where it says [microfilm reel] and 
the print version shows [volume]. You are likely to see this for other 
titles as well because each format has been cataloged with its own LCCN. 
You are also likely to see additional records with [online resource] 
identified as the format as more and more titles are available as 
ePrints or online.

I hope this helps answer your additional questions a bit more. Please 
reach out if you have any other questions.

Thank you,

Hi, Kelly:


At the risk of bombing your inbox with more emails than you want,
what is your relationship with Wikipedia and other Wikimedia Foundation
projects like Wikidata?


I ask, because I've logged over 20,000 edits in Wikimedia Foundation
projects since 2010, and I would happily try to answer questions about
Wikidata and other Wikimedia Foundation projects. I have NOT organized
an edit-a-thon, but I've made presentations at conferences with people
who have, and I would happily try to help organize such if you could
find a group of people who want to work to improve this US Newspaper
database. I think it would be good to establish links between this US
Newspaper database and Wikidata, with appropriate procedures so changes
to one could be evaluated for acceptance into the other.


FYI, John Peter Zenger's famous "New-York weekly journal" (1733-1751)
appears TWICE in your database with lccn = 2009252748 and sn83030211 and
ONCE in Wikidata WITHOUT an lccn, even though many other Wikidata items
have an lccn. See:


https://www.wikidata.org/wiki/Q23091960


There's a "WikiProject Newspapers" on Wikipedia and a companion
"WikiProject Periodicals" on Wikidata:


https://en.wikipedia.org/wiki/Wikipedia:WikiProject_Newspapers/Wikidata


https://www.wikidata.org/wiki/Wikidata:WikiProject_Periodicals


I've tried to connect with others on those projects, so far with only
limited success. However, you may know that almost anyone can change
almost anything on Wikipedia and other Wikimedia Foundation projects.
What stays tends to be written from a neutral point of view citing
credible sources. They have problems with vandals, but the problems are
usually easily controlled. This makes Wikipedia and Wikidata very
useful platforms for cleaning up databases like your US Newspaper dataset.

Hello Spencer,

Thank you for sending along your follow-up questions.

I'm glad to hear the json view will work for you. It was recommended to 
me that you limit your requests to 500 rows at a time. And a developer 
here at LC suggests the following regarding rate limiting:

“To avoid being blocked by the server, the current rate-limiting rules 
restrict un-cached requests to URLs starting with 
https://chroniclingamerica.loc.gov/search/ 
<https://chroniclingamerica.loc.gov/search/> to 120 requests every 10 
minutes from a single IP address.”

So, I think if you limited each of your requests to 500 rows at a time 
with the proper pauses, then you should be able to access what you need.

As for the csv view, I checked on this as well, and was informed that 
the csv view was not implemented for all url formats. The csv view was 
only implemented for this view: 
https://chroniclingamerica.loc.gov/newspapers/ 
<https://chroniclingamerica.loc.gov/newspapers/>and urls resulting from 
US Directory search results - for e.g. if you wanted to narrow down your 
search results by state, city, date range, etc. found at this link: 
https://chroniclingamerica.loc.gov/search/titles/ 
<https://chroniclingamerica.loc.gov/search/titles/>. So, if you wanted a 
csv and limited your search by state ( for example: 
https://chroniclingamerica.loc.gov/search/titles/results/?state=Alaska&county=&city=&year1=1690&year2=2022&terms=&frequency=&language=&ethnicity=&labor=&material_type=&lccn=&rows=20&format=csv 
<https://chroniclingamerica.loc.gov/search/titles/results/?state=Alaska&county=&city=&year1=1690&year2=2022&terms=&frequency=&language=&ethnicity=&labor=&material_type=&lccn=&rows=20&format=csv> 
), you could append &format=csv to the search result url and get the csv 
to automatically download. But, if your search results ended up being 
over a couple thousand titles, then the system would probably time out.

Hello, Kerry:


Thanks for the reply. Can you please give me some further guidance
on two thing "so that the system is not overwhelmed"?


1. The max size in a small batch?


2. Any limit on the number of small batches in a second or minute?


I've found that I can download small batches under program control
using "RCurl::getURL" in R (programming language) using, e.g.;


https://chroniclingamerica.loc.gov/search/titles/results/?rows=20&page=2&format=json


With this, I can control the batch size with "row=20" vs. "row=50"
vs., e.g., "row=1000". A naive search says there are 157520 "results".
With "row=1000", this would require 158 calls. With "row=20", it
would require 7876 calls. Before I start, I need to decide which fields
I want; I don't need them all.


Thanks,
Spencer Graves


p.s. I tried appending "&format=csv" and got "Error 504 Ray ID:
7220896da85e86e7 • 2022-06-27 19:19:53 UTC Gateway time-out". I used:


https://chroniclingamerica.loc.gov/search/titles/results/?state=&county=&city=&year1=1690&year2=2022&terms=&frequency=&language=&ethnicity=&labor=&material_type=&lccn=&rows=20&format=csv


I can get what I want using json so do not need csv. However, I
thought you might want to know that I was unable to get csv to work.

Hello Spencer,

Thank you for contacting the Library of Congress about searching the US 
Newspaper Directory. I wanted to follow up with you regarding your 
request to output the data in a machine readable format.

It looks like you were provided the link to the API documentation for 
the website: About the Site and API 
<https://chroniclingamerica.loc.gov/about/api/>. Scroll down to the 
section with the heading, Searching the directory and newspaper pages 
using OpenSearch. This section describes the search functionality and 
structure for the US Newspaper Directory in more detail. It is possible 
to return your directory searches in json format by appending 
&format=json to the end of the url. It is also possible to return search 
results in csv format by appending &format=csv to the end of the url, 
but I would strongly suggest that you do this in small batches by 
putting limits on your search so that the system is not overwhelmed.

So, from the search page for the US Newspaper Directory 
<https://chroniclingamerica.loc.gov/search/titles/> you could 
potentially limit your search based on state and city, or date range, 
and/or even frequency. Then once you've completed the search, you can 
add &format=csv to the end of the url to automatically download a csv of 
those records. The resulting csv will contain several fields/headers: 
lccn, title, place of publication, start year, end year, publisher, 
edition, frequency, subject, state, city, country, language, oclc 
number, and holding type. I think these fields include the information 
you were looking for. But, again, I would like to stress that you put 
limits on your search before creating the csv so as not overwhelm the 
system.

Please let me know if you have any other additional questions.

Best wishes,

Dear Mr. Queen:


Thanks for the reply. I'm still confused. I downloaded and
installed Docker Desktop and "docker-compose.yml" and ran their "Getting
Started" Tutorial, but I don't see what to do next.


I repeat: I'd like to analyze "U.S. Newspaper Directory,
1690-Present" (https://chroniclingamerica.loc.gov/search/titles/), which

Mr. Graves,

Programmatic access to the data forChronicling America 
<https://chroniclingamerica.loc.gov/>and possibly the U.S. Newspaper 
Directory <https://chroniclingamerica.loc.gov/search/titles/>can be 
found on theAbout the Site and API 
<https://chroniclingamerica.loc.gov/about/api/>page in various formats. 
Also, please note that Chronicling Americacontains newspapers published 
from 1777-1963, but does not include everyU.S. newspaper published in 
that time period.

Please let me know if I can be of further assistance.

Dear Mr. Queen:


Can we simplify this to just giving me the data behind "U.S.
Newspaper Directory, 1690-Present"
(https://chroniclingamerica.loc.gov/search/titles/) in a machine
readable format, e.g., csv or xlsx or a MySQL database?


As I mentioned in my original email, a naive search of that without
restrictions returned 157520 titles in 7876 pages with up to 20 titles
per page giving date ranges in at least some cases. I could probably
write software to scrape those 7876 pages from your web site and combine
them into a data file.


I have a PhD in statistics, I have been using the R programming
language and similar software for decades. This includes publishing
tutorials on how to analyze data like this on Wikiversity.[1] I'd like
to do something similar with this. I could help make your data more
useful to others and discuss with you how we might prioritize
improvements like accessing the other sources you mentioned.


Thanks very much for your reply.

Mr. Graves

Your request is a little more complex than it first appears and requires 
extensive research. A variety of resources should be consulted to 
determine the circulation statistics of newspapers published prior to 
1851. You will need to check newspaper union lists and newspaper 
histories. Union listspresent lists of newspapers in geographic 
arrangement according to place of publication, and specify which 
libraries or other institutions hold collections of those newspapers and 
the dates of their holdings. These can also be useful for tracking title 
changes throughout a newspaper's history. Newspaper 
historieslikeAmerican Journalism: A History: 1690-1960 
<https://lccn.loc.gov/62007157>(Mott),The Penny Press 
<https://lccn.loc.gov/2004043078>(Thompson), andThe Press and America 
<https://lccn.loc.gov/99044295>(Emery et al.) may not include 
circulation statistics, but they do document the diversity and progress 
of newspaper publishing, including notable newspapers of the era. 
Newspaper histories also cover the history of the printers and printing 
of newspapers in a state, county, or region more generally, and provide 
more condensed histories of the editors, journalists, and evolution of 
the newspapers in a specific area. Newspaper histories and union lists 
should be available at most large public or university libraries. More 
information about union lists, newspaper histories, and researching 
newspapers in general can be found in theU.S. Newspaper Collections at 
the Library of Congress 
<https://guides.loc.gov/united-states-newspapers/introduction>research 
guide (see Reference Sources).

Please let me know if I can be of further assistance.

Original Question

How can I get counts of the numbers of newspapers by year in the US, and 
preferably also elsewhere?

A search of "U.S. Newspaper Directory, 1690-Present" 
(https://chroniclingamerica.loc.gov/search/titles/) returned 157520 
titles in 7876 pages with up to 20 titles per page giving date ranges to 
the extent that it's known. If I can get a data file (e.g., csv or xls), 
I can summarize. I could also use data on circulation and frequency and 
especially parent company for multiple newspapers published by the same 
company, to the extant that such is available.

I'm interested in this, because McChesney quoted Tocqueville in 
suggesting that the US had more newspapers per person (or per million 
population) prior to 1851 than at any other time or place in history. 
I'd like to evaluate that claim with data to the extent that I can. See 
"https://en.wikiversity.org/wiki/Social_construction_of_crime_and_what_we_can_do_about_it#Newspapers_1790_-_present".
