Here's the list of my internet resources. When I provide a link to a specific article, I'll include an abbreviation of the name of the internet resource where I found it in parentheses after the title of the article. If I first locate a PubMed link while searching Goog, which happens frequently, I'll identify it as (Goog-PubMed) and give the PubMed, rather than the Goog, link. I am still exploring these and will continue to add links from them as I find time.
Kimball's online textbook (Goog-Kimball)
This is a very complete Biology textbook which the author has put online. I'll be giving links from it frequently. Although I found it through Google, I'll identify the source of the links as (Kimball).
Many of the links are to abstracts; only some are to full length articles. However, frequently the abstracts tell you all that you need to know. When you click on the link for a particular article, PubMed will usually provide, to the right of the name of the article, both the links to 5 "Related articles" and also the links to any PubMed Central articles which cited the article you've accessed. The PubMed Central articles are all full-length, rather than abstracts. Following either of these sets of links will lead to other links which will lead to other links, etc.
Although many journals are accessible online, their articles can also be accessed through PubMed, and it will be those links that I'll be giving. However, there are a few resources, such as BHL, NRC and CogP, below, which are not indexed by PubMed and which will have to be searched individually.
PubMed lists their links with the most recent first. If you're just starting to learn about a subject, I would recommend reversing this and looking at the oldest references first. This will familiarize you with the issues and vocabulary as they have developed through time. Working from oldest to newest will make it all much more understandable.
Biodiversity Heritage Library (BHL)
This is huge. It offers 14,905 titles, 36,604 volumes and 16,027,896 pages on line, all for free. I found it by searching Google for my all time favorite: 'The Brain of the Tiger Salamander' by C. Judson Herrick. For an ongoing discussion of the salamander brain based primarily on this book, please see the '04.00 Salamander' section.
Thank you, Google.
National Research Council, Canada (NRC)
The NRC offers free online access to the contents of 16 journals published in Canada. All 16 journals are fully searchable from the home page using the window on the right, and all articles have a link to a full length PDF. Just be sure to specify the 'Journals' option when you search.
Cognitive Science Print Archives
A collection of papers in the cognitive sciences not indexed by PubMed.
Google Scholar (GoSch)
I'd seen references to this service, but this is the first time I've ever looked at it. Some of the links are to full length articles, but some are just to abstracts. To see what would happen, I searched the term 'amphioxus'. I got 12,300 hits.
When I use the Google search window, which is the default on my Firefox browser, I'll identify the results with the abbreviation (Goog). When I searched 'amphioxus' on Google rather than GoSch, I got 365,000 hits.
GoSch vs Goog vs PubMed
All of the articles in PubMed are written by professionals for professionals. They're the real nitty-gritty, but they're also somewhat advanced. Searching PubMed for 'amphioxus' yielded 665 hits. Although GoSch claims 12,300 hits for 'amphioxus' and Goog claims 365,000, my Firefox would show me only the first 1,000 GoSch hits and the first 550 Goog hits.
I prefer Goog to GoSch. Although both find links to technical articles, most, perhaps even all, of these are also to be found through PubMed. Unlike GoSch, Goog also finds a large number of articles that are well written in plain english for the general public. These 'plain english for the general public' articles are not available through PubMed, so you can only find them through Goog.
If a topic is completely new to you, Goog is the place to start. Most frequently, Goog will give a link to Wikipedia at the top of it's list. I'm a devoted Wiki fan, but you don't have to stop there. There are more 'plain english for the general public' articles out there than just Wikipedia.
Massachusetts Institute of Technology (MIT)
The Massachusetts Institute of Technology (MIT) has put many of its courses online. The link, below, leads to the full list of their 1800 online courses:
In general, I was disappointed with these classes. What started out as their psychology department has been transformed into the 'Brain and Cognitive Sciences' department, and they seem to have lost track of the fact that there is more to psychology than just the brain and cognition.
Nevertheless, there were still some books worth looking at and many links worth following. I've retained the things I liked in the 18 courses I reviewed and discarded the rest.
