# Library FAQs

 Definition/Summary Any PF member may create a Library entry. Once you have created it, it will "go into moderation" for several days or weeks while "moderators" approve it (and maybe hack it about a bit). Only you and the moderators will be able to see it and amend it. When it reappears, you, or anyone else, may suggest changes to it, in the "Add a comment" field. The unique feature of the PF Library is its AUTOLINKING: when the title appears (followed by a space) in any post (past or future) in any PF sub-forum, it will appear underlined, and with a clickable link to the Library entry. The following answers to FAQs may help you (you should particularly note that the Library software does not allow all "tags" in all fields, and so some of what you type may appear mangled).

 Extended explanation Definition/Summary: No italic bold underline or smilies , or non-standard characters such as ∞ or ≥ or π or … (if you need them, you must put them in itex: $\boldsymbol{v}\ \infty\ \geq\ \pi\ \dots$). No tex, only itex (so do not use fractions or powers). Keep it reasonably short and clear … you can extend the definition in Extended explanation. Equations: No italic bold underline or smilies , or non-standard characters such as ∞ or ≥ or π or … (if you need them, you must put them in tex or itex). Obviously, keep this mostly for equations. Keep it short … do not define the symbols you are using if they are standard (for example, r m G t g µ), or obvious. Put each equation on a new line (usually). Equations or symbols in a text line should be in itex, not tex. Vectors should be in bold (use "\boldsymbol{}"), not with arrows (except for vectors between two specific points). LATEX TIPS: Most equations will be short, and there is plenty of space, so experiment with increasing the spacing by using "\ " for a large space and "\," for a tiny space … for example "\ =\ " instead of just " = ". Huge brackets may be made by inserting "\left" and "\right" before "(" and ")" or "[" and "]". For a huge bracket at one end of a line but not at the other (because the equation carries on over more than one line), type "\left." at the beginning, or "\right." at the end, instead of the "missing" bracket. If necessary, you can put an equation in colour by putting COLOR tags outside the tex or itex tags. For latex symbols, see http://web.ift.uib.no/Teori/KURS/WRK/TeX/symALL.html and for latex basics, see http://www.maths.tcd.ie/~dwilkins/LaTeXPrimer/ Scientists: First and last name, then years of birth and death in brackets. Use the "link" tag to link to (usually) the wikipedia page. List in order of date of birth. Extended explanation: Feel free to experiment. The following is suggested: Headings in bold, followed by a colon (:). Highlight colour red (middle of the left-hand-side of the colour palette). Use sparingly, for fundamental concepts. Reduced size: click size "1" for bits which are slightly off-topic, or for chatty bits about scientists, or the origin of words etc., or just for variety. Smilies: use sparingly. Indent: use to break up the text, expecially when it is starting to look too boring. Units: use SI units, except in topics where it is normal to do otherwise. Citations and links: If it needs a citation, it's probably too obscure for PF Library. Links to outside articles or books for a more detailed treatment may be useful.
