Mission of :
PPIGB is an internet resource guide for all aspects of plant pathology,
applied entomology and related fields. It is intended as starting point
for scientists, students and all who are interested in phytopathology to
explore the internet. The compilation of websites is divided into thematic
categories in which every Link is followed by a brief description of the
content of the website. Every Link is also accompanied by an additonal
keyword set, which is not visible in PPIGB but which is searchable (for
more information see Features).
PPIGB is updated every week. New entries will be available on mondays. You will find the date of the last update on the starting page.
The original homepage of PPIGB is located at the Department of Horticulture, University of Hanover. Its location is: http://www.ifgb.uni-hannover.de/extern/ppigb/ppigb.htm.
How are the websites compiled? (I) The author searches the net frequently for new websites of interest by using the power of several search engines. (II) Every user of PPIGB has the possibility to submit a new link by using the On-Line form or by sending me an e-mail. After a new link is found the author will visit this website and browse through it. After visiting the website a description is written, which contains in general the following information: Title of URL, Location, available information, additional information and tips.
Resource Evaluation and Description
In PPIGB only websites will be compiled which contain relevant information on
subjects related to it. Where possible you will find information about the
author/institution and their location. The description of the content will
give you information about what you will find on that website. In most cases
a number of keywords is given or a short paragraph on the mission or content
of that site. Where possible the author will take this information from the
website itself. After a new resource was included to PPIGB the author will try
to contact the author(s) of the website, so that he can verify/change the given
The author of PPIGB will give further information about Specific Features like high quality pictures, how to use the website, loading time, usability, and organization where it seems to be appropriate. Extraordinary sites will be marked as a TIP (see Features).
In order to keep the link information updated the websites will be visited
from time to time to confirm that the description is in accordance with the
content of the website. If a link is definitly broken (not only that the server
is down for a shorter or longer period), I will try to verify the
URL or to find the new location of it. In cases where I failed to find
the URL it will be deleted from PPIGB. These broken links will be kept on
my machine to try them from time to time. If you find a broken link in PPIGB
please e-mail me. If your website has moved please submit the new URL.
Broken URLs are indicated in PPIGB and can also be found in section "LOST-NOT-FOUND".

How to use ?
I want to keep PPIGB as simple as possible. For example I will only use graphics
where they are appropriate. The PPIGB starting screen is divided into two frames.
on the left you will find the MENU frame and on the right side the TEXT frame.
While you navigate through PPIGB this frame will not change and will not be reloaded. Here you will find the different sections of PPIGB (in the moment more than 20 like Mycology). A mouse click on one section will display the content of this section in the TEXT frame on the right side. At the bottom of the MENU frame you will find the PPIGB icon which will takes you back to the starting screen. Here you will also find buttons for searching PPIGB or for submitting an URL, meeting and position.
The starting TEXT frame will give a short introduction and information on the last update (PPIGB will be updated every week), Links to the mirror sites of PPIGB, What's New, approvements and awards of PPIGB.
After you have selected a category from the MENU frame the content of this selected section will be displayed in the text frame. In cases where necessary a sub menu will appear (like for section Institutes/Departments). Links in each section will be displayed in alphabetic order. On the right side of the heading you will find again the button for adding a new URL. In some cases an icon will appear with the link. See Features for explanation. At the bottom you will find again the PPIGB icon, which will take you back to the start and the name of the author with e-mail function. If a page is divided into sub-pages you will also find a "Top of Page" function, which will take you back to the sub menu.
Wherever you find the PPIGB Icon it will redirect you to the starting page of PPIGB.

The Features of :
PPIGB has some features which will be explained briefly:
The What's new Page: PPIGB will be updated every week. here you will find the new entries since the last update. Also featured on this page: The TIP of the month. This is a website, which contains very useful information and is very well organized. The TIP of the Month is intended to promote an extraordinary website. And last but not least the Notes from the Authors. Here you will get the laatest informations on PPIGB (e. g. new features, major changes, problems...)
The meeting and position announcment service: The author offers every user the possibility to announce a meeting or position without having an own website. The required www-pages will be created by the author and placed on the server of PPIGB. These services are free of charge. More details? Go to Feedback.
The buttons and Icons:
|The new entries will be marked in their section with one of these icons.|
|Extraordinary websites which are of special interest are marked by this icon. Sites marked as a TIP will be visted frequently by the author to confirm the usability of these sites.|

|This are the buttons for the different On-Line Forms of PPIGB. They are intended to simplify the feedback to the author. For a detailed description go to the Feedback.|
|A feature of PPIGB available from July 27, 1997. The SEARCH buttons enables a full text search of PPIGB. You can search for any keywords or for URLs. The Perl based script will be improved over time and new features will be added. See author notes for recent changes on this function.|
|The PPIGB icon. In most cases it will take you back to the starting page of PPIGB. If you should get lost in PPIGB (but I am sure that this will not happen) click on it. This button was introduced, because many Search-Engines also find single sections of PPIGB. And for those coming to PPIGB from such a Search-Engine this button will lead them to PPIGB.|
