### Research Libraries for Accessing Zotero

https://github.com/zotero/publications/issues/71

> This project is not developed anymore though it is maintained (and still in use). You won't be able to display entire library on your page using this library (without modifying it), it only works for "My Publications".
>
> Web Library is actively developed and we're considering making a [version that can be embedded](https://forums.zotero.org/discussion/82607/embedding-the-zotero-web-library#latest).
>
> For lower-level library, there is also [zotero-api-client](https://github.com/tnajdek/zotero-api-client) - which is what Web Library is using under the hood. It is actively developed and works in both Node and browser environment.

Start by reviewing issue #44 and the linked Zotero API research, including zotero-api-client and the Web Library embedding discussion. Determine which access approach can pull the needed Zotero items; done means the items are retrieved and displayed, with the remaining tasks and scope clarified.
