The bibliography style you choose determines how names, such as titles and authors will be formatted. You should therefore type the complete name and leave the formatting to .
If an entry has more than one author, then an "and" will separate the names; names in braces are considered as one name and will not be stylised by .
According to the bibliography style you choose, a title may be capitalised by (even if you had typed it in in lower case). In general titles of books are capitalised, while titles of articles are not. If you want a specific word or letter to remain capitalised, then enclose it in braces.
