[Eril-l] CLOCKSS vs Portico?

[Electronic Resources in Libraries discussion list]

Hi Melissa,
This is my understanding of how these work -

Portico works in several ways:  they trigger some content as fully open access, and some content is triggered for members-only (all members get all member-only triggered content, even if you were not an original subscriber/buyer with the publisher itself).  How content is triggered depends on the agreements between the publishers & Portico. See their triggered list/Kbart<https://www.portico.org/coverage/triggered-content/>. For example, a while back they opened up the Morgan & Claypool Colloquium books<https://www.portico.org/news/portico-access-alert-13-morgan-claypool-ebook-series/> as fully open access, which were titles we previously bought from the original publisher.  They also offer to provide perpetual access<https://www.portico.org/for-participants/#pca> at the Portico platform if Portico has the content and the publisher can't provide it to you on their platform and you're supposed to have the perpetual (if you're a Portico member).

Clockss triggers all of its content as fully open access, and you don't need to be a member to reap those benefits. However the hard work of their staff & infrastructure requirements of course benefit from folks supporting their efforts in general. They recently triggered the journal Heterocycles<https://clockss.org/triggered-content/heterocycles/>, which was a title some of our campuses had asked about, and I was happy to tell them it had been preserved by Clockss.

They are both great organizations providing a vital service, and I think supporting many avenues for digital preservation is beneficial (if you have the funds). But Portico does provide specific members-only services & access to some content.  I'm not sure how much overlap there may be across publishers that are preserving content in one, or the other, or both services.  Here's a useful comparison chart<https://clockss.org/wp-content/uploads/2020/02/Comparison-CLOCKSS-GLN-Portico-30July2019.pdf> although the data is a few years old by now.

CAUTION: EXTERNAL EMAIL
Hi,
We cannot afford to be a paying member/supporter of both CLOCKSS and Portico. Right now we pay Portico.
I just got a solicitation email to join CLOCKSS and it mentioned that everything it makes available (lightening dark archive) it does as Open Access for everyone. I believe that Portico only makes the materials available to paid members. Someone please correct me if I'm wrong about any of this.

Should we be switching to CLOCKSS?  What other factors besides price should we be considering?
