Availability
The ISSN Register is not freely available for interrogation on the web but is available by subscription. There are several routes to the identification and verification of ISSN codes for the general public.
- the print version of a periodical typically will include the ISSN code as part of the publication information
- most periodical websites contain ISSN code information
- derivative lists of publications will often contain ISSN codes; these can be found through on-line searches with the ISSN code itself or periodical title
- WorldCat permits searching their catalog by ISSN by entering "issn:"+ISSN code in the query field. One can also go directly to an ISSN's record by appending it to http://www.worldcat.org/ISSN/, e.g. http://www.worldcat.org/ISSN/1021-9749. This does not query the ISSN Register itself but rather shows whether any Worldcat library holds an item with the given ISSN.

Famous quotes containing the word availability:
“Since ... six weeks ago, there has been no day in which I have not had letters and visits on the subject of my nomination for the Presidency.... I say very little. I have in no instance encouraged any one to work to that end.... I have said the whole talk about me is on the score of availability. Let availability do the work then.”
—Rutherford Birchard Hayes (1822–1893)
