Recently I came across a journal post and also a profile page where the users put together a list of usefull identification guides for certain groups of animals. I think this is a great way of providing usefull information to other users and also to keep an organized list of resources for yourself. Therefore, I’d love to gather a similar list. I already have a couple of online resources on my list, but I wanted to add more things before “posting” it on my profile or my journal.
Does anyone have suggestions of guides/identification keys/resources that should be on the list? I’m mostly looking for online and open access resources (so that everyone can access them), but feel free to suggest any guide. Also, as I’m based in Portugal, I’m mostly looking for European guides, but I’m happy to take all suggestions!
