From Collaborative RCE Knowledge Library
Navigating the Library
The main way of navigating the library is by using the interactive navigation tree at the left side of the screen. Click the plus/minus icons to expand/collapse any given category, and click directly on the category names to look at all the items in any given category.
The items in each category will be sorted by their current rating (and alphabetically when equal ratings occur). You can (and are encouraged to) contribute with your own vote for the rating of each item in the library that you are familiar with. To submit your own vote, simply click the star corresponding to the rating you want to vote for in the listing for the item in question (e.g., if you think the item deserves a score of 4 out of 5 possible, simply click the fourth star, and then follow the instructions on the screen). You can also change your vote at any later time, by simply repeating this voting procedure for the item.
Also, at the bottom of each category page you will find a list of all subcategories of the category in question, these too interactively expandable if they in turn would have any subcategories.
The library main page is at the very root of the category hierarchy, and thus you can find all categories in the library in its expandable subcategory list.
The three main top-level categories below this root level are named "Categorized by Knowledge Area", "Categorized by Knowledge Type" and "Categorized by Platform". Just as with any category in the library (which are really category tags, as mentioned on the main page), a item can occur under both these categories (and/or any of their sub-categories). Which one of these three roads you choose to follow when searching for a item only depends on what's most suitable for you at the moment. Do note though that even though a item often occurs under all these top-level categories, all of them don't! Normally, the "Categorized by Platform" category will contain somewhat less items than the other two, since it will not include any items that are applicable to more than one platform (say, e.g. a more platform-generic text about unpacking).
