To assist librarians in making decisions about maintaining print holdings of e-journal content being preserved in Portico, we offer a Holdings Comparison service offered at no cost to participating and non-participating libraries. A Holdings Comparison also lets librarians:
In order to compare your library’s journal holdings to the content in the Portico archive, we will need a list of the ISSNs associated with the titles that you hold.
This list of ISSNs may be provided to us in either of these two formats:
It is acceptable to supply us with an Excel spreadsheet that contains additional columns of data other than those listed in the samples above. When you are ready to initiate a holdings comparison, these title listings can be sent as an attachment to email@example.com or submitted through the Compare Holdings Form page.
The ISSN may be formatted in any of the following ways:
Portico will perform the comparison and return to you an Excel spreadsheet explaining the status of each provided ISSN and containing the following information:
|Library Columns||Columns provided in the original submission file|
Whether or not the title is committed to the archive with three possible status levels:
|Portico P-ISSN||Print ISSN Portico has for this title|
|Portico E-ISSN||E-ISSN Portico has for this title|
|Portico Title||Title that Portico has for this match|
|Portico Publisher||Publisher who is providing content to Portico|
|Portico Post-Cancellation Access||Whether the publisher has designated Portico as a post-cancellation access mechanism|
|Portico Holdings||List of issues for this journal that are preserved in the Portico Archive at this moment (note that more content may be in queue)|
|Portico Years||Time frame of the content for this journal that is in the Portico Archive (note that more content may be in queue)|
An email containing your updated spreadsheet will be emailed to you.
