Data Entry


Welcome to the User Guide to UCR Herbarium's Search-Form Databases

The search forms for the UCR Herbarium's lichen and vascular collections assume that the user is not troubled by the restrictions on the search to the entries whose characteristics matched the values entered into the fields provided on the page. For example, the entry of a collector's patri-family name in the Collector's Last Name field and the word "foothills" in the Locality field followed by the clicking of the "Submit" button at the bottom of the page will get those specimens in the database whose collector has the patri-family name entered and whose locality description contains the word "foothills." Those specimens without both will be excluded from the data presented. Adding the matri-family name will only hinder the search rather than restrict the search to the individuals with those with both the patri-family and matri-family names.

For those of you who would need a more sophisticated search, such as those lichen specimens found in either Germany or Austria, you will need to use the Web-interactive interface for the lichens database available on another webpage. Both database systems are capable of sophisticated searches. However, either interface have their individual restrictions on the searches that can be done.

On the search form, the entries for many fields do not need to be fully spelled out. The beginning first letters will do if you do mind risking getting more than you were aiming for. Keep in mind that if you enter a date in "Search by Date" section, nothing should be entered into "Search by Date Range" section since the specific date will either logically limit the range to that date or preclude any selection of specimens. Similarly, if you enter a date range in the "Search by Date Range" section, nothing should be entered into the "Search by Date" section for the same reason.

In the search results' Condensed Presentation of the specimens' data, the up-pointed and down-pointed white triangles will sort the specimens based on the field name they surround. Clicking the Collector's name will get you all the specimens in the database collected by that particular collector. Clicking the Accession number of a specimen will get you an expanded presentation of the data for that single specimen. You can move from a condensed format to an expanded format and back again by clicking the relevant link at the top.

The web database server requires a web browser that can handle cascading style sheets, JavaScript and Unicode (specifically, UTF-8). Most, if not all, current browsers meet those requirements.

If you observe any errors, please let us know and corrections will be made as soon as possible. We have made every effort to create a database that accurately reflects the content of our herbarium, but we know that various sorts of errors have crept into the dataset. If anything looks suspicious to you, please let us know!

The basic design for this particular web database was derived from Rancho Santa Ana Botanic Garden Herbarium (RSA) web database (currently under going servicing). We wish to thank RSA for their help.
