Note about searching:
You are using the Crossref search API described at https://api.crossref.org When you search with query terms, on Crossref servers they are not searching full text, or even abstracts of articles, but only what is available in the data that is returned to you. That is, they search article titles, authors, etc. For some discussion on this, see https://gitlab.com/crossref/issues/issues/101
Rate limits:
Crossref introduced rate limiting recently. The rate limits apparently vary,
so we can't give a predictable rate limit. As of this writing, the rate
limit is 50 requests per second. Look for the headers X-Rate-Limit-Limit
and X-Rate-Limit-Interval
in requests to see what the current rate
limits are.
The Polite Pool:
To get in the polite pool it's a good idea now to include a mailto
email
address. See docs for more information. TLDR: set your email in an env var CROSSREF_EMAIL
.
URL Encoding:
We do URL encoding of DOIs for you for all methods except Serrano.citation_count
which doesn't work if you encode DOIs beforehand. We use ERB::Util.url_encode
to encode.
Install
Release version
gem install serrano
Development version
git clone git@github.com:sckott/serrano.git
cd serrano
rake install
Setup
Crossref's API will likely be used by others in the future, allowing the base URL to be swapped out. You can swap out the base URL by passing named options in a block to Serrano.configuration
.
This will also be the way to set up other user options, as needed down the road.
Serrano.configuration do |config|
config.base_url = "https://api.crossref.org"
end
We recommend you set your mailto
email here so you can get in the "polite pool" which gives you faster rate limits:
Serrano.configuration do |config|
config.mailto = "jane@doe.org"
end
Or use an env var with name CROSSREF_EMAIL
Examples
Use in a Ruby repl
Search works by DOI
require 'serrano'
Serrano.works(ids: '10.1371/journal.pone.0033693')
Search works by query string
Serrano.works(query: "ecology")
Search works using metadata filters. See CrossRef filter docs.
Serrano.works(query: "ecology", filter: { has_abstract: true })
Search journals by publisher name
Serrano.journals(query: "peerj")
Search funding information by DOI
Serrano.funders(ids: ['10.13039/100000001','10.13039/100000015'])
Get agency for a set of DOIs
Serrano.registration_agency(ids: ['10.1007/12080.1874-1746','10.1007/10452.1573-5125'])
Get random set of DOIs
Serrano.random_dois(sample: 100)
Content negotiation
Serrano.content_negotiation(ids: '10.1126/science.169.3946.635', format: "citeproc-json")
Use on the CLI
The command line tool serrano
should be available after you install
~$ serrano
Commands:
serrano contneg # Content negotiation
serrano funders [funder IDs] # Search for funders by DOI prefix
serrano help [COMMAND] # Describe available commands or one spec...
serrano journals [journal ISSNs] # Search for journals by ISSNs
serrano licenses # Search for licenses by name
serrano members [member IDs] # Get members by id
serrano prefixes [DOI prefixes] # Search for prefixes by DOI prefix

# Many DOIs
~$ serrano works "10.1007/12080.1874-1746,10.1007/10452.1573-5125"
## if above two dois in a file called dois.txt
~$ cat dois.txt | xargs -I{} serrano works {}
# output JSON, then parse with e.g., jq
