I like Zotero - it works as a plugin for Firefox or as a standalone version. You can save references directly from the website without an extra download step, tag things, add notes, save pdfs and sync across multiple computers. I now have a huge library and searching is easy. When it comes time to write a paper, it has plugins for Word and LibreOffice to help with your references.
How big are the moulds? You could try a silicon ice cube tray? Label the bottom of the tray/each individual cube mould with a marker pen to help identify which oct mould is which. If you buy silicon, you can cut away the centre line between two ice cube moulds to make a long/rectangular storage space for a whole brain/a saggital section. https://www.amazon.com/dp/B07KWR369C/ref=sspa_dk_detail_7?psc=1&pd_rd_i=B07KWR369C&pd_rd_w=0BixG&pf_rd_p=8a8f3917-7900-4ce8-ad90-adf0d53c0985&pd_rd_wg=yeWfZ&pf_rd_r=YFNK51N90NBRZA1BA87J&pd_rd_r=f966daf2-9abb-11e9-ba5f-0d77a0619401

One of the authors has more of a journalism background, while the other has more of a scientific background. They're a great team! The book is a fast read and the principles I learned significantly improved my ability to communicate scientific concepts with a non-scientific audience.
