AAPG Datapages  (Info)
| Producer: | American Association of Petroleum Geologists | |
|---|---|---|
| Description: | Search journals published by the American Association of Petroleum Geologists, including AAPG Bulletin, AAPG Special Volumes, Bulletin of Canadian Petroleum Geology, Journal of Petroleum Geology, Journal of Sedimentary Research. Coverage varies from 1917 to present. Also includes publications by several regional groups. | |
| Usage Tips: | Combining Terms: Use quotation marks " " to search for a phrase. Using Boolean operators (AND, OR, NOT) are another way to combine terms but not search them in any particular order. Wildcards: The ? operator acts as a single character wildcard. For example: a search for M?d will match words like Mud, Mad, Med, Mod, Mid and so on. The asterisk * acts as a multiple character wildcard. For example: a search for Petrol*m will match Petroleum, Petrolatum and so on. For help using this resource, click here. | |

Annual Review Of Earth And Planetary Sciences  (Info)
Connect to: Annual Review of Earth and Planetary Sciences
| Producer: | Annual Reviews | |
|---|---|---|
| Description: | Synthesizes the vast amount of primary research literature and identifies the principal contributions in Earth Sciences in one annual volume. Search or browse. Full text access from 1996 to present. | |
| Usage Tips: | Combining Terms: Use double quotes " " to indicate phrase searching. For example, a search for "synaptic plasticity" finds articles in which the two words appear as a phrase. Likewise, a search for synaptic plasticity without the quotation marks finds articles that contain both words, apart or together. Boolean operators (AND, OR, NOT) can also be used to sharpen your search. Wildcards: Two wildcard characters are supported: the asterisk (*) and the question mark (?). The '?' stands for any character within the search string and the '*' stands for zero or more characters at the end of a search word. For example, a search for b?nd finds bond, bend, band, bind, plus all their plurals and '-ing' forms. A search for adeno* finds adenovirus, adenocarcinoma, adenohypophysis, adenosine, etc. For more help using this resource, click here | |

Annual Reviews  (Info)
| Producer: | Annual Reviews | |
|---|---|---|
| Sources: | Sources | |
| Description: | An especially valuable form of secondary literature. Articles in the Annual Review series are comprehensive, dependable, and offer sizeable bibliographies; if you can find an article on your topic, it will probably point you to most of the relevant primary literature which had appeared up to its publication date, and give you a firm basis for understanding the evolution of research traditions in that subfield. | |
| Usage Tips: | For a more specialized search, see the individual Annual Review titles listed under corresponding subject guides.
For help using this resource, click here. Not all topics are to be found. If you get nothing useful, try a more general search. Wildcards: Two "wildcard" characters are supported -- the asterisk (*) and the question mark (?). The '?' stands for any character within the search string and the '*' stands for zero or more characters at the end of a search word. No word used in a query may start with a wildcard. Wildcards do not work inside quotation-mark-grouped phrases. Example: a search for "b?nd" finds bond, bend, band, bind plus all their plurals and "-ing" forms. Combining Terms: Any multi-word phrases that are to be treated as single search items must be entered in double quotation marks. For example "synaptic plasticity" finds articles in which the two words appear as a phrase. Words within parentheses are evaluated together before the whole search is evaluated. Thus, a search for "impaired driving" or "drunk driving" and opinion or attitude can be sharpened as ("impaired driving" or "drunk driving") and (opinion or attitude). | |

| Usage Tips: | Wildcards: Wildcards are used to represent from zero to nine additional characters in a search term. A pound sign # represents a single character. A question mark ?, alone or with a number, represents from zero to nine additional characters. Example: Searching for wom#n with return records containing woman and women. Searching for colo?r will return records containing color, colour, colonizer, and colorimeter. Combining Terms: Group terms in parentheses () to specify the order in which they will be combined. Without parentheses, terms will be combined in left-to-right order. Wildcards: Use an asterisk * as a wildcard operator. For example, a search for securit* retrieves records that contain security, securities, securitization, etc. A pound sign # represents a single character. A question mark ?, alone or with a number, represents from zero to nine additional characters. For example, a search for wom#n records containing woman and women. A search for colo?r records containing color, colour, colonizer, and colorimeter. Phrases: Insert phrases into quotation marks " " to indicate the order the words should appear in your search. | |
